<P CLASS=para>
This abstract class is the superclass of all input streams.
It defines the basic input methods that all input stream
classes provide.

<P CLASS=para>
<tt CLASS=literal>read()</tt> reads a single byte or an array or subarray
of bytes. It returns the byte read, or the number of bytes
read, or -1 if the end-of-file has been reached.
<tt CLASS=literal>skip()</tt> skips a specified number of bytes
of input. <tt CLASS=literal>available()</tt> returns the number of bytes
that can be read without blocking. <tt CLASS=literal>close()</tt> closes
the input stream and frees up any system resources
associated with it. The stream should not be used after
<tt CLASS=literal>close()</tt> has been called.

<P CLASS=para>
If <tt CLASS=literal>markSupported()</tt> returns <tt CLASS=literal>true</tt> for a given
<tt CLASS=literal>InputStream</tt>, that stream supports
<tt CLASS=literal>mark()</tt> and <tt CLASS=literal>reset()</tt> methods. <tt CLASS=literal>mark()</tt>
marks the current position in the input stream so that
<tt CLASS=literal>reset()</tt> can return to that position as long as no
more than the specified number of bytes have been read
between the <tt CLASS=literal>mark()</tt> and <tt CLASS=literal>reset()</tt>.
See also <tt CLASS=literal>Reader</tt>.
